  9. Return finalizationRegistry.

  GetPrototypeFromConstructor ( constructor, intrinsicDefaultProto )

  3. Let proto be ? Get(constructor, 'prototype').
  4. If Type(proto) is not Object, then
    a. Let realm be ? GetFunctionRealm(constructor).
    b. Set proto to realm's intrinsic object named intrinsicDefaultProto.
  5. Return proto.
